I am using https://source.codeaurora.org/external/imx/imx-atf/log/?h=lf_v2.4

Since the driver sending SMCC commands to ATF isn't doing that, I
assume it's safe to use the linux power-domain drivers with the ATF
from NXP's kernel.

If you can point me to the repo you think I should be using, I'll give it a try.

Do you know if the mainline TF-A repo v2.5 works too?
https://github.com/ARM-software/arm-trusted-firmware/tree/v2.5

That's good to know.

I just built it into U-Boot:

NOTICE:  BL31: v2.5(release):v2.5

The Etnaviv driver is still loading without hanging

Tim,

Which version of Nano do you have?  Not all Nano SoC's have a GPU from
looking at the datasheet [1] .  I am using MIMX8MN2CVTIZAA (Nano Solo)
